ASTM D5415-95(2020)

This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the
Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
Designation: D5415 − 95 (Reapproved 2020)
Standard Test Method for
Evaluating Load Containment Performance of Stretch Wrap
Films by Vibration Testing
This standard is issued under the fixed designation D5415; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
